My salesman told me that the lenses of the the speedo/tach gauge cluster of my '09 E scratch very easily and that I should be very careful cleaning them and definitely not use any ammonia-based glass cleaner on them. He recommended cleaning them with a just a little water on a Q-tip swab.
Based on what he said, I've yet to clean them at all. What do you guys do ?
